Her Majesty passed away at Balmoral surrounded by her family on Thursday.
The decision means that Liverpool will have to reschedule their clash with Wolves at Anfield later in the season.
Finding a gap in the Reds' already busy calendar may be difficult.
Certainly, there aren't any available dates before the hiatus of the campaign for the World Cup.
Final Premier League matches take place on Saturday 12 November and Sunday 13 November before the tournament starts in Qatar on Sunday 20 November.
Until then, Jurgen Klopp's side are already playing twice a week in the Premier League and Champions League - as well as the third round of the Carabao Cup against League One outfit Derby County (Tuesday 8 November).
Meanwhile, there is an international break taking place later this month.
After the World Cup, the fourth round of the Carabao Cup takes place on Tuesday 20 December.
Then the busy festive period ensues before the FA Cup third round begins on Saturday 7 January 2023, with the fourth round going ahead on Saturday 28 January.
The first possible date that seems realistic for Liverpool would be on either Tuesday 17 January or Wednesday 18 January.
The following Tuesday 24 January/ Wednesday 25 January is also free as things stand.
However, that is when the first leg of the Carabao Cup semi-final is scheduled for, with return matches taking place the following week. If either side gets that far, with Liverpool the current holders, those dates will be busy.
Then last 16 of the Champions League gets started the following week. Some first-leg ties are played on 14/15 February, with others the following week.
